ANGIOEDEMA EREDITARIO DA DEFICIT DI C1-INIBITORE: IDENTIFICAZIONE GENETICA PRECOCE IN UN NUCLEO FAMILIARE
2010
EDEMA EMORRAGICO ACUTO DELL'INFANZIA: UN CASE REPORT
2019
Un lattante di 6 mesi maschio giunge alla nostra osservazione per comparsa di lesioni maculo-papulari alle guance estesesi, in poche ore, ai quattro arti ed evolventi in manifestazioni purpuriche su cute edematosa senza segno della fovea. All’EO all’ingresso si evidenziavano inoltre: angioedema dei padiglioni auricolari, aspetto a coccarda delle lesioni aventi diametro max di 2 cm con coinvolgimento anche dello scroto, cute del tronco e mucose integre, assenza di segni neurologici. Due giorni prima del ricovero e della comparsa delle manifestazioni cutanee il piccolo aveva presentato febbre (T max 39,5°C) e faringite trattata con amoxi-clavulanato. Esami al ricovero: PCR mossa (2,3 mg/dl; V…
Anti-inflammatory and antiallergic activity in vivo of lipophilic Isatis tinctoria extracts and tryptanthrin.
2006
The effects of a supercritical CO2 (SFE) extract, a dichloromethane (DCM) extract from Isatis tinctoria leaf and the alkaloidal constituent tryptanthrin were studied in acute and subchronic experimental models of inflammation. The SFE and DCM extracts showed anti-inflammatory activity in the carrageenan-induced acute mouse paw oedema (ED50 values of 78 mg/kg and 165 mg/kg P. O., respectively) and in the acute tetradecanoylphorbol acetate (TPA)-induced mouse ear oedema in oral (62% and 32% oedema reduction at 100 and 125 mg/kg, respectively) and topical application (37% and 33% reduction of oedema at 0.5 mg/ear). In contrast, tryptanthrin showed no significant anti-inflammatory effect. The D…
Anti-Inflammatory Activity of Unusual Lupane Saponins fromBupleurum fruticescens
1998
Extracts from Bupleurum fruticescens were examined for oral and topical anti-inflammatory activities. The BuOH extract proved to be active against carrageenan and tetradecanoylphorbol acetate acute edemas and allowed the isolation of three saponins identified by spectroscopic techniques as 3 beta-O-(O-alpha-L-rhamnopyranosyl-(1-->4)-O-[beta-D-glucopyranosyl- (1-->6)]-O-beta-D-glucopyranosyl)lup-20(29)-ene-23,28-dioic acid (fruticesaponin A), 3 beta-O-(O-alpha-L-rhamnopyranosyl-(1-->4)-O-beta-D-glucopyranosyl) lup-20(29)-ene-23,28-dioic acid 28-O-beta-D-glucopyranosyl ester (fruticesaponin B), and 3 beta-O-(O-alpha-L-rhamnopyranosyl-(1-->4)-O-[beta-D-glucopyranosyl- (1-->6)]-O-beta-D-glucopy…
Classification of SD-OCT volumes with multi pyramids, LBP and HOG descriptors: application to DME detections.
2016
This paper deals with the automated detection of Diabetic Macular Edema (DME) on Optical Coherence Tomography (OCT) volumes. Our method considers a generic classification pipeline with preprocessing for noise removal and flattening of each B-Scan. Features such as Histogram of Oriented Gradients (HOG) and Local Binary Patterns (LBP) are extracted and combined to create a set of different feature vectors which are fed to a linear-Support Vector Machines (SVM) Classifier. Experimental results show a promising sensitivity/specificity of 0.75/0.87 on a challenging dataset.
Carbon monoxide improves cardiac energetics and safeguards the heart during reperfusion after cardiopulmonary bypass in pigs
2004
Ischemia-reperfusion injury, a clinical problem during cardiac surgery, involves worsened adenosine trisphosphate (ATP) generation and damage to the heart. We studied carbon monoxide ( CO) pretreatment, proven valuable in rodents but not previously tested in large animals, for its effects on pig hearts subjected to cardiopulmonary bypass with cardioplegic arrest. Hearts of CO-treated pigs showed significantly higher ATP and phosphocreatine levels, less interstitial edema, and apoptosis of cardiomyocytes and required fewer defibrillations after bypass. We conclude that treatment with CO improves the energy status, prevents edema formation and apoptosis, and facilitates recovery in a clinical…
Chapter 35 Complex regional pain syndrome
2006
Publisher Summary This chapter describes complex regional pain syndrome (CRPS) as changes of muscles and bones distant from the primary tissue damage. It causes both acute pain and excitation of the sympathetic nervous system. The chapter classifies CRPS into two clinical types: the “primarily warm” type, which usually develops post-traumatically and in which skin temperature is increased on the affected side; and CRPS cases, which manifest with a cold skin from the beginning. This “primarily cold” type more often develops after minor trauma or even spontaneously. The chapter reviews that “primary cold” CRPS is harder to treat and tends to become chronic. Symptoms of CRPS are not stable; th…
LAAE-14, a new in vitro inhibitor of intracellular calcium mobilization, modulates acute and chronic inflammation.
2003
Abstract A new lipidic acid-amido ether derivative (LAAE-14) able to reduce dose-dependently the calcium increases mediated either by calcium ionophore ionomycin, by the endoplasmic reticular Ca 2+ -ATPase inhibitor thapsigargin, or by the chemotactic tripeptide N -formyl- l -methionyl- l -leucyl- l -phenylalanine (fMLP), in human neutrophils as well as in murine peritoneal macrophages, but not ATP, has been evaluated as a potential anti-inflammatory drug. This compound attenuated leukocyte activation by means of its inhibitory effect on the respiratory burst elicited in both types of cells by 12- O -tetradecanoyl phorbol 13-acetate, by inhibition of the degranulation process induced by cyt…
Anti-inflammatory profile of dehydrocostic acid, a novel sesquiterpene acid with a pharmacophoric conjugated diene
2005
Sesquiterpene acids are natural products that, in contrast with the thoroughly studied sesquiterpene lactones, have received little pharmacological attention. A good source of this class of compounds is Inula viscosa (Asteraceae), a plant with documented anti-inflammatory effects. The present paper gives the results of our investigations on the biochemical mechanisms involved in the anti-inflammatory activity of one such compound, dehydrocostic acid. The most salient findings were that in vitro dehydrocostic acid inhibits leukotriene B(4) production (IC(50)=22 microM), elastase activity (IC(50)=43 microM) and bee venom phospholipase A(2) activity (IC(50)=17 microM). Furthermore, this sesqui…
